In my first experience with sockets in perl, I've written my DNS client utility for CGI, which I've named "DNS Crawler". A heck of a lot of help information and functionality was included into the script. Since it does not yet support zone transfers, it is not released. But first I want all kinds of people to "crawl" all over the dns system looking for bugs or improvements that can be made.

Here's some of the things I want you to look for:

1) Broken links2) Help links that returns a "no definition" message3) improvements in style that may be made, such as colors and layout.4) If you don't understand something and there's no help available for it.5) suggestions to make things more convenient, or smooth, or professional.6) mispelled words or bad case, or hard-to-read fonts.7) obvious bugs such as crashes8) strange error messages that may be better written

Thank you very much for your report! I was beginning to think everybody was either gonna test out the script and say nothing, or ignore it.

I did some sniffing to see why. The script sent the UDP packet to the server. Then a ICMP packet was sent back in response to tell me that the port is unavailable. However, the script interpreted the ICMP as incoming data, but it failed to retrieve any data cause there wasn't any. And since I'm finding out that perl's socket error descriptions are gay, all it said was "Unknown Error" in reference to the "Recieve" action that took place.

So now I changed it so that when it fails to read UDP data, it assumes it is an invalid dns server. It will now say this:

"The 'Server' field is not a valid DNS server"

(btw, whoever has been sending OMV requests on the dns tool, please speak up. I want to talk to you.)

Ok, I've seen a lot of people misunderstand what the SERVER field and the NAME fields are in the program. I repeat, and emphasize STRONGLY that you read the help on the initial page! Just click on a topic to learn. Most words are linked and defined.

hah! even if nobody says anything perhaps I can get SOME help from people's experimentations. It was kinda amusing, some poor chap very obediently read the help for 'server' and 'name' and STILL didn't send his query right. I've modified the help information for those 2 terms to make things more clear on how to use them.

Don't worry, I plan on making a newbified submit form to make sending queries less confusing.

A person uses a domain that ends with 'OMV.com' for his internet connection. He also sent queries relating to the OMV domain. There's also the website 'www.omv.com' which is incredibly professional, and bears many different language versions - not sure what it's for though. Due to his know-how in querying his own domain, I wanted to talk to him. Happy nosey?
